just got 3.73s and Kooks LT's put on - been taking it easy on the throttle to give the gears time to break in. Yesterday I got impatient and gave it some gas from a dig and heard/felt some banging/clunk sounds from under the car
The car drives great otherwise, but under any duress/hard shift I get either one or two of these sounds, and I can feel them through the car. I broke my tranny mount in my old LT1 and it feels similar from what I remember, so I'm hoping it's just that - does that sound right???? Should I be bracing myself for something worse?

I would check your tq arm mount first. Ive ripped 3 in the last 6 months.

Worth a try good luck

Check your trans mount. I could also be your pipes banging on your mid-cross member (black bar with 4 bolts). I had the same issue, and felt like someone was hammering down below while driving!...lol
